Best way to learn Angular 8

Before you actually start learning Angular, you need to understand a few concepts such as:
  • Difference between traditional web-applications and single-page applications
  • AngularJS drawbacks
  • What is Angular?
To begin with, let me first tell you what is the difference between traditional web-applications and single-page applications?
Traditional Web-apps:

I’m sure you will remember that in the past, whenever you would request for a web page, the page used to reload entirely in order to load the data as shown in the image above. This model is referred to as Traditional-W➨eb Application (TWA). The biggest problem of this was of course time-consumption.
To overcomes this problem, SPA’s or Single-Page Applications model was introduced. SPAs are browser applications that are similar to mobile applications that come with dynamic interactions. They have much lesser refresh rates when compared to TWA’s. Take a look at the image below that depicts the SPA model where the client requests a URL from the server after which the complete page is loaded to the client’s browser. Now, this does not require page reloading:


So what is Angular JS?
It is an open-source framework for front-end development that is based on the JavaScript Framework. It is used to create SPA’s and was developed by Google in the year 2002.
Drawbacks of AngularJs:
AngularJs became very popular but, it did nit have many necessary features that were being offered by other JavaScript frameworks.
Some of them are:
  • Large bundle size
  • Issues with Performance
  • No support for mobile devices
Therefore it was not able to resolve these problems which in turn led to the development of a new JavaScript framework which was much more stable and faster.
Angular:
In order to resolve the issues mentioned earlier, Google developed Angular. This also is an open-source JavaScript framework. It was a complete rewrite of AngularJs and worked on a differently.
So, what is Angular?
Angular is undoubtedly one of the most popular JavaScript front-end frameworks that are used by many & programmers to create and manage web applications. It is written in Typescript which is an open-source programming language. The latest version of Angular now is Angular 8.

JDK 25: The new features in Java 25

 Java Development Kit (JDK) 25, scheduled for release in September 2025, is set to introduce several significant enhancements. Here's an overview of the notable features: 1. Stable Values API (Preview): This feature introduces stable values—objects holding immutable data treated as constants by the Java Virtual Machine (JVM). By allowing greater flexibility in initialization timing compared to final fields, stable values aim to improve application startup times. They enable performance optimizations akin to constant-folding, previously exclusive to JDK code, and ensure thread-safe, single-time initialization. This decouples the creation of stable values from their initialization without significant performance penalties.  2. Removal of 32-bit x86 Port: JDK 25 plans to eliminate both the source code and build support for the 32-bit x86 port, which was deprecated in JDK 24. Maintaining this port has become less beneficial, especially with the challenges in keeping it updated wit...

what is circuit breaker in microservice

   A circuit breaker is a design pattern used in microservice architecture to improve the resilience and fault tolerance of the system. In a microservice architecture, multiple services work together to deliver a business function. When a service is not available, the downstream services depending on it may start to fail as well, leading to a cascading failure. A circuit breaker helps prevent cascading failures by monitoring the status of the dependent services. If a dependent service is not responding, the circuit breaker trips and redirects the traffic to a fallback mechanism, such as a cache or a default response. The circuit breaker periodically attempts to reconnect to the dependent service, and once it's available, it resumes directing traffic to it. The circuit breaker pattern helps prevent failures from spreading across the system, improves the availability of the overall system, and can help reduce the load on dependent services.
